Description

  The present invention relates to a monitoring control device used in a remote monitoring control system that performs load monitoring control by communication.

  Conventionally, in order to perform remote monitoring and control of loads such as multiple lighting fixtures and air conditioners installed in houses and buildings, transmission signals including switch on / off information are transmitted via signal lines, and load power is supplied. A technique for opening / closing a relay to be turned on / off by a transmission signal is known. This type of remote monitoring and control system includes a terminal unit including one or more operation terminals having switches and one or more control terminals having relays for turning on / off a load. There is a central control type equipped with a center device. The transmission unit, the operation terminal, and the control terminal are connected to a two-wire signal line, and the transmission unit uses the terminal address set individually for the operation terminal and the control terminal. Recognize each control terminal separately.

  The transmission unit includes a memory that stores a control table that is a data table in which operation terminals and control terminals are associated with each other by addresses. When the transmission unit is notified of the switch on / off information in any of the operation terminals, the transmission unit relays the control terminal associated with the operation terminal by the control table. A transmission signal including an instruction command for opening and closing is transmitted. Then, the relay is opened and closed in the control terminal that has received this transmission signal. Therefore, the load is controlled according to the on / off state of the switch.

  Here, in general, each operation terminal has a switch of a plurality of circuits, and a plurality of loads are connected to each control terminal. In addition, the control table provided in the transmission unit can be associated with each switch and load. Each operation terminal unit assigns a load number to each switch, and identifies the only switch actually operated by using the terminal address of each operation terminal unit followed by the load number as the switch address. I can do it. Similarly, in the control terminal, a load number is assigned for each load, and a load address is added to the terminal address of each control terminal after the load address.

  Further, in the control table, it is possible to tie the switch and the load one-to-one or one-to-many. For example, when a luminaire is used as a load, the transmission unit performs individual control for turning on and off one luminaire with one switch and turning on and off a plurality of luminaires with one switch. It is possible to set with batch control. Such collective control includes group control and pattern control. In group control, a range of a load to be controlled is associated with a switch in advance, and the load in the range is turned on or off collectively by operating one switch. In the pattern control, the range of the load address to be controlled and the on / off state of the load corresponding to each address are associated with the switch in advance, and the load in the range is turned on or off by operating one switch. To.

  In order to perform the group control or pattern control, in the transmission unit control table, the group number or pattern number corresponding to the switch that performs group control or pattern control is associated with the address of the load in the range to be controlled. When a switch for group control or pattern control is operated, the transmission unit expands the address of the load to be controlled by collating with the control table, and further determines the load on / off state. Thereafter, an instruction is given to the control terminal having the address obtained by referring to the control table.

  As a monitoring control device used as an operation terminal of the above-described remote monitoring control system, a screen display unit composed of a liquid crystal display, and an operation input unit composed of a transparent touch switch arranged on the screen of the screen display unit, There has been proposed a device including a control unit that performs load control according to an operation input of an operation input unit associated with display contents of a screen display unit and a screen display according to a load state (for example, , See Patent Document 1).

  In such a monitoring control device, the control unit counts the time when there is no input in the operation input unit, and when the measured time exceeds a predetermined time Δt, the power supply to the screen display unit is cut off. At the same time, the operation clock of the control unit is stopped and the control unit shifts to a standby state in which only minimum functions such as interrupt processing are enabled (see FIG. 7). When an input is generated in the operation input unit in the standby state, the control unit returns to a normal state in which it can be operated by performing its own return process and the return process of the screen display unit. Thus, the power consumption is reduced by shifting to the standby state when the user is absent or not operating when the monitoring control apparatus is not used.

  However, in the conventional restoration method as described above, since the restoration processing of the control unit and the screen display unit is performed after the input is generated in the operation input unit, the time required to return to the normal state becomes long and is used. There was a problem that the convenience of the elderly was impaired. On the other hand, as another return method, there is a method of cutting off only the power supply to the screen display unit in the standby state as shown in FIG. In this restoration method, only the restoration process of the screen display unit is performed after the input is generated in the operation input unit, and the normal state is restored. Therefore, it is necessary to return to the normal state as compared with the restoration method shown in FIG. Time can be shortened.

Note that the standby state is not necessarily limited to each of the above standby states, and may be a standby state in which various means for cutting off the power supply to the communication circuit unit 4 are combined.

  Hereinafter, the operation of the present embodiment will be described with reference to the drawings. First, the transition from the normal state to the first standby state and the return from the first standby state to the normal state will be described. As shown in FIG. 3A, when an input is generated in the operation input unit 2 or the switch operation unit 20 in a normal state, the control unit 3 executes a process according to the operation. When the input from the operation input unit 2 and the switch operation unit 20 does not occur for a predetermined period, the control unit 3 makes a transition from the normal state to the first standby state. Here, even when the period in which there is no input in the operation input unit 2 and the switch operation unit 20 does not reach the predetermined period, if there is no human body detection in the human body detection unit 5, the control unit 3 starts from the normal state. Transition to the standby state.

  Thus, when there is no input for a predetermined period in the operation input unit 2 or the switch operation unit 20, not only the transition to the first standby state is made, but also when there is no human body detection in the human body detection unit 5, Since the transition to the first standby state is made, it is possible to reduce the power consumption by shortening the time required for the transition from the normal state to the first standby state.

  As shown in FIG. 3B, when an input is generated in the operation input unit 2 or the switch operation unit 20 in the first standby state, the control unit 3 makes a transition from the first standby state to the normal state. In addition, even when there is no input from the operation input unit 3 and the switch operation unit 20, when the human body detection occurs in the human body detection unit 5, the control unit 3 shifts from the first standby state to the normal state.

  Thus, when an input to the operation input unit 2 or the switch operation unit 20 occurs, the normal state can be restored, and even if no input to the operation input unit 2 or the switch operation unit 20 occurs, the human body detection unit 5 When human body detection occurs, the normal state can be restored, so that the time required for the return from the first standby state to the normal state can be shortened and the convenience of the user can be improved.

  Next, the transition from the normal state to the second standby state and the return from the second standby state to the normal state will be described. As shown in FIG. 4A, when an input is generated in the operation input unit 2 or the switch operation unit 20 in the normal state, the control unit 3 executes a process according to the operation. When the input from the operation input unit 2 and the switch operation unit 20 does not occur for a predetermined period, the control unit 3 makes a transition from the normal state to the second standby state. Here, even when the period when there is no input at the operation input unit 2 and the switch operation unit 20 does not reach the predetermined period, when the human body detection unit 5 does not detect the human body, the control unit 3 moves from the normal state to the second state. Transition to the standby state.

  Thus, when there is no input for a predetermined period in the operation input unit 2 or the switch operation unit 20, not only the transition to the second standby state is made, but in the case where there is no human body detection in the human body detection unit 5, the first time is shortened. Therefore, the time required for the transition from the normal state to the second standby state can be shortened, and the power consumption can be reduced. In addition, when making a transition from the normal state to the second standby state, instead of making a transition to the second standby state at a stretch, first the transition is made to the first standby state, and then after a certain period of time, the second standby state You may make it make it change to.

  As shown in FIG. 4B, when an input is generated in the operation input unit 2 or the switch operation unit 20 in the second standby state, the control unit 3 transitions from the second standby state to the normal state. Even when there is no input from the operation input unit 3 and the switch operation unit 20, when the human body detection occurs in the human body detection unit 5, the control unit 3 shifts from the second standby state to the normal state.

  Thus, when an input to the operation input unit 2 or the switch operation unit 20 occurs, the normal state can be restored, and even if no input to the operation input unit 2 or the switch operation unit 20 occurs, the human body detection unit 5 When the human body detection occurs, the normal state can be restored, so that the time required for the return from the second standby state to the normal state can be shortened and the convenience of the user can be improved.

  Next, the transition from the normal state to the third standby state and the return from the third standby state to the normal state will be described. As shown in FIG. 5, when an input is generated in the operation input unit 2 or the switch operation unit 20 in the normal state, the control unit 3 executes processing according to the operation. When the input from the operation input unit 2 and the switch operation unit 20 does not occur for a predetermined period, the control unit 3 makes a transition from the normal state to the third standby state. Here, even when the period in which there is no input in the operation input unit 2 and the switch operation unit 20 does not reach the predetermined period, if there is no human body detection in the human body detection unit 5, the control unit 3 starts from the normal state to the third state. Transition to the standby state.

  Thus, when there is no input for a predetermined period in the operation input unit 2 or the switch operation unit 20, not only the transition to the third standby state is made, but also in the case where there is no human body detection in the human body detection unit 5, the first time is shorter. Therefore, the time required for the transition from the normal state to the third standby state can be shortened, and the power consumption can be reduced. In addition, when making a transition from the normal state to the third standby state, instead of making a transition to the third standby state at a stretch, the transition is first made to the first standby state, and then the second standby state after a certain period of time. It is also possible to make a transition to the third standby state after a certain period of time.

  As shown in FIG. 6A, when an input is generated in the operation input unit 2 or the switch operation unit 20, the control unit 3 shifts from the third standby state to the normal state. Here, when there is no input in the operation input unit 2 and the switch operation unit 20 and human body detection in the human body detection unit 5 occurs, the control unit 3 makes a transition from the third standby state to the normal state all at once. Instead, first, a transition is made to the second standby state. As shown in FIG. 6B, when an input is generated in the operation input unit 2 or the switch operation unit 20 in the second standby state, the control unit 3 makes a transition from the second standby state to the normal state. On the other hand, when there is no input in the operation input unit 2 and the switch operation unit 20 and human body detection in the human body detection unit 5 occurs, the second standby state is maintained. When there is no human body detection for a predetermined period, the control unit 3 makes a transition from the second standby state to the third standby state again.

  Thus, the combination of the presence / absence of input to the operation input unit 2 or the switch operation unit 20 and the presence / absence of human body detection in the human body detection unit 5 changes from the third standby state to the normal state through the second standby state. Since the return and the second transition from the second standby state to the third standby state can be performed as appropriate, power consumption can be reduced without impairing the convenience for the user.

  As described above, in the present embodiment, a plurality of standbys including the presence / absence of human body detection within an arbitrary range are performed instead of making a transition to a standby state depending only on the presence / absence of input to the operation input unit 2 as in the past. Since any one of the states is shifted to the standby state, it is possible to balance power consumption reduction and user convenience in the standby state.
